Best enchant for 80 twink?

Sorry if this has been answered before:

I just got hold of a bjams and I'm uncertain which enchants are best for level 80s. Is it the same for PvP and PvE? Dancing steel looks enticing but I've heard 80s actually might scale better with windsong. Or should I just stick with runeforging? If so, which one and why?

Windsong for all specs. Depends on whether you're interested in soloing/pve or pvp. For pve/soloing windsong is best because you get alot of ap from vengance so extra 3.3k won't mean that much compared to having +35% crit, or +45% haste and parry bonus you'd get from the strenght is overkill. For pvp windsong is still better but not by such a large margin.
